Why:
- An audit for the new unkin-agent bot (org-wide write) found repos with
no branch_protection at all, so the agent (or anyone with write) could
push straight to their default branch.
- The rest of the estate protects default branches; these repos were the gap.
How:
- Add enable_push: false + approval_whitelist_teams: Owners on each active
repo's default branch, matching the estate's most common convention
(PR-only; Owners can still open and approve).
- Omit status checks on these repos as none run CI, so a required context
would permanently block merges.
- Leave the 8 archived repos untouched: they are read-only, nothing can push
to them, and branch-protection creation on archived repos is rejected.
